D-Lysine Hydrochloride CAS 7274-88-6

1. D-Lysine hydrochloride, the D-isomer of the essential amino acid lysine, is primarily used as a fundamental building block in chemical synthesis and pharmaceutical research for preparing polylysine polymers, which find application in lysine-based polypeptide gels and films .
2. D-Lysine hydrochloride CAS 7274-88-6 serves as a chiral intermediate in the synthesis of 3-amino-azepan-2-one and other enantiomerically pure compounds for drug development and biochemical studies .
3. D-Lysine hydrochloride is employed in research investigating amino acid metabolism, stereospecific biological interactions, and as a negative control in studies focused on the biological activity of L-lysine .
4. Researchers utilize this product for R&D purposes only, where its unique D-configuration makes it valuable for studying enzyme stereoselectivity and protein structure-function relationships .

1. D-Lysine hydrochloride must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment; recommended storage at RT (room temperature) or at -20°C for long-term stability, protected from light .
2. D-Lysine hydrochloride CAS 7274-88-6 is considered non-hazardous under normal handling conditions but may cause skin, eye, and respiratory irritation; it has a GHS NFPA health rating of 1 (exposure would cause irritation with only minor residual injury) .
3. Personnel must wear chemical-resistant gloves, safety goggles with side-shields, and protective clothing when handling this substance, ensuring adequate ventilation in work areas and avoiding formation of dust and aerosols .
4. Keep away from incompatible materials such as strong oxidizing agents, strong acids, and strong bases to prevent decomposition ; the compound has WGK Germany 3 (high water hazard potential) and should not be released into the environment .

1. Isolate the spill area, ensure adequate ventilation, and wear full personal protective equipment including chemical-resistant gloves, safety goggles, and suitable dust respirator (type N95 or P1 filter) when D-lysine hydrochloride is released .
2. Collect D-Lysine hydrochloride CAS 7274-88-6 by sweeping or vacuuming without creating dust using non-sparking tools, or absorb with inert materials such as diatomite or universal binders, and place into suitable closed containers for disposal .
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure; decontaminate surfaces using appropriate methods; prevent the product from entering drains or water courses .
4. Dispose of collected material as non-hazardous waste according to local, state, and federal environmental regulations through licensed chemical destruction or controlled incineration .

1. D-Lysine hydrochloride is not classified as highly flammable with an NFPA fire rating of 1 (materials that require considerable preheating before ignition); under fire conditions, hazardous decomposition products include toxic fumes of carbon monoxide, carbon dioxide, nitrogen oxides (NOx), and hydrogen chloride gas .
2. Use D-Lysine hydrochloride CAS 7274-88-6 water spray, dry chemical powder, carbon dioxide, or alcohol-resistant foam to extinguish fires involving the product, selecting the extinguishing media appropriate for surrounding materials .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning D-lysine hydrochloride due to hazardous decomposition gases generated by thermal decomposition .
4. During combustion, may emit irritant and toxic fumes; move containers from the fire area if safe to do so, cool exposed containers with water spray from a protected location, and contain fire runoff to prevent environmental contamination and pollution .
